I made simple case for model that my wife was doing - garden cafe. Due to that cleaning from dust is much complex when there are a lot of tiny details i wanted to make it easier.

Case still requires acrylic sheet (or some other transparent material:

Top x1: 174x174
Depending on printer settings it should go tight but i also used some UV glue to lock it in place.

Walls x4: 180 x 205 (i cut to 179 and 203/204 for easier fit)

Rows for acrylic sheet are 1.5mm so 1mm is good.

In my case i took transparent sheet from really cheap ikea frames 21 x 25 or something like this that were on sale.
